    up until 2000 2000-2005 2005-2007 Jan 2008 PhD NOAA postdoc Asst. Professor

    Daniel Jacob Allen Goldstein & Inez Fung

    Research Interests:• Aerosol sources, composition and chemistry• Biogenic and anthropogenic influences on chemistry and climate• Intercontinental transport of pollution

    I am a global atmospheric chemistry modeler.

  • SOA-RELATED RESEARCH

    Anthropogenic EmisssionsBiogenic Emissions

    Climate (Precip,Oxidants,T)Climate+Emissions

    Anthropogenic Land-Use Change

    HOW WILL SOA RESPOND TOFUTURE CLIMATE EMISSIONS

    AND LAND-USE CHANGE?

    Coupled land-atmosphere model used to examine how SOA responds to future climate and emissions. Project a 43% increase in burden in 2100 (A1B) [Heald et al., submitted]

    WHAT DO AMBIENT OBSERVATIONS TELL US ABOUT SOA?

    Two studies focused on ACE-Asia (off of Japan) and ITCT-2K4 (NE North America) aircraft campaigns demonstrate large gaps in our understanding of SOA (as simulated by models) [Heald et al., 2005; 2006]

  • CONTINUING/ONGOING DIRECTIONS

    What can satellite observations of AOD tell us

    about SOA?

    What can the suite of detailed gas/aerosol phase in situ observations

    tell us about OC sources? How can we improve global model

    representations of SOAformation?

    BVOC global emissions responseto climate/environment (eg. CO2)and impacts on chemistry-climate
